    TLDR M-CSF-stimulated myeloid cells can cause alopecia areata in mice.
    The study demonstrates that M-CSF-stimulated CD11b+ myeloid cells can induce alopecia areata (AA) in C3H/HeJ mice, highlighting their significant role in the disease's pathogenesis. Researchers found that these cells, derived from AA-affected skin or cultured with M-CSF, can activate B lymphocytes, leading to increased splenocyte proliferation and IgG levels. The findings suggest that, alongside T cells, myeloid cells and B cell activation are crucial in AA development. The study provides insights into the cellular mechanisms of AA and suggests that targeting M-CSF and CD11b+ myeloid cells could be a potential therapeutic strategy.
